Alexandre Rodríguez Guerra holds a PhD from the University of Salamanca with an extraordinary doctoral award and is a lecturer in the Department of Galician and Latin Philology at the University of Vigo. In recent decades he has participated regularly in research projects at Galician and national level, articulated around three fundamental axes: historical linguistics (approached from the syntactic, palaeographic or graphematic perspectives), computer resources and tools for the Galician language, and the lexicon (from the neological and lexicographic perspectives).
He has organised scientific activities with international repercussions, such as the III Colloquium on Historical Linguistics and the International Symposium ‘E irei madr’a Vigo’, and has been a member of the organising committees of several international congresses. His research career includes several monographs (among them, Miguel de Unamuno e a lingua galega), the (co)edition of books such as Neoloxía e lingua galega: teoría e práctica, Lingüística histórica e Dialectoloxía: coordenadas do cambio lingüístico or The Vindel Parchment and Martin Codax, as well as articles and book chapters focused on four main areas of research: (i) the historical syntax of Galician, (ii) the lexicon and neologisms of Galician and other Romance languages, (iii) medieval Galician graphematic and (iv) the external history of the Galician language.
He has co-directed two doctoral theses and is currently supervising another two at a very advanced stage of completion. He coordinates with Xosé M.ª Gómez Clemente the Observatory of Neology of the Galician Language at the University of Vigo, and also coordinates since 2022 the research group Technologies and Applications of the Galician Language (TALG). He is co-editor of the journal Locus Criticus. Textual Criticism on the Net and directs the magazine Cumieira das Letras.
